hey,<br><br>I have been tasked w/reviewing/testing/etc our processes for managing encrypted backups & it got me to thinking "what's the right # of keys to deploy (global master pair? one per client? one per application?)? how often should they be rotated? where/how should they be stored?", etc.<br>
<br>my 1st inclination is to write a script to generate a metric 5h1+-ton of key pairs, burn them onto a bunch of CDs and distribute them to clients for one-time use but is that thermonuclear overkill? obviously nobody wants to end up on /. but on the other hand ending up w/a backup you can't decrypt/restore is arguably worse (far IMO).<br>
<br>what are the accepted best practices for key management (generation, rotation, storage, recall, etc) for backups? any good white papers, books, blogs, etc?<br><br>any info appreciated!<br>
